I was told that the resin (yellow) of the White Pine is used medicinally in kidney complaints, and 
is found very effective in stricture and retention of urine. A gentleman says he finds it gives great 
relief in very aggravated cases, when three or four doses are usually sufficient. He dissolves the resin in 
alcohol, and gives from 20 to 30 drops in water as a dose. 
Coming to other species we have 
Araucaria Bidwilli, Hook., “ Bunya Bunya.” 
Bor an examination of the resin of this plant, see Maiden.* * * § I there stated 
that the exudation of this Pine would probably be found similar to that of 
A. Cunninghamii if collected under similar conditions. 
The gum resins of Araucarias are also dealt with by Lauterer,f who gives 
analyses of the exudations of A. Bidwilli and A. Cunninghamii. See also a special 
paper by Lauterer on A. Bidicilli.% 
Araucaria Cookii, R.Br. 
Hr. Schuchardt, of Gorlitz, informed me that he had found sugar in the resin 
of Araucaria Cookii from New Caledonia (Lr. of 11/2/90). 
Araucaria Rulei, B.v.M. 
Prof. E. Heckel has recently published a research on the gum-resin of this 
New Caledonian species. § 
Araucaria brasiliana, A. llich. 
“ The resin of Araucaria brasiliana exudes from the old trees, especially if the bark has been 
damaged by beetles, and hardens rapidly in the air. Dull white or dark brown irregular pieces, varying 
in size from that of a bean to that of a walnut, and elongated drops. Has a faint lustre, and a smooth 
waxy fracture. Smells balsamic, somewhat turpentine-like, and tastes resinous, biting and aromatic ; 
sticks to the teeth. Heated on platinum foil it carbonises without melting completely, evolving an odour 
of incense. In a flame it takes fire and burns, leaving five per cent, of ash. The resin dissolves to the 
extent of about two-thirds in water and one-third in alcohol; ether and chloroform take up only traces of 
volatile oil, gum, and vegetable albumen, uncrystallizable sugar, and four different resins. From the 
mixture of resins, freed from volatile oil and substances soluble in water, cold alcohol takes up alpha, beta, 
and gamma resins, leaving araucaric acid undissolved. The gamma resin is precipitated from the alcoholic 
solution by acetate of copper, and the beta resin from the filtrate by alcoholic neutral acetate of lead, 
whilst the alpha resin remains in solution.” Further particulars of these bodies are given. ( Gmelin , xviii, 19.) 
The analysis of the resin of the Chilian species should now he brought up to 
date, but is of special interest in view of the interest attaching to those from 
Australian Araucarias. 
Size.— Up to 150 feet high and a diameter of 4 or 5 feet on the Richmond 
River, where it attains its greatest development. It is much smaller on the Clarence 
and Bellinger. 
“ Spars for ship3 may be obtained in any quantity from 80 to 100 feet in length ; in some instances 
the tree attains a height of at least 150, and from 4 to 5 feet in diameter.”—(C. Moore, in London Exh.. 
1862, Report.)
